Abstract: Inspection of pipelines and confined industrial environments is a challenging and critical task, especially in areas that are hazardous or inaccessible to humans. This project presents the design and development of a four-legged spider robot integrated with a camera system, controlled using an Arduino microcontroller, for efficient detection of damages and defects in pipelines and constrained spaces.

The robot is designed with a quadruped locomotion mechanism, enabling it to navigate uneven surfaces, narrow passages, and complex terrains where traditional wheeled robots may fail. Each leg is actuated using servo motors, providing stability and flexibility for movement in confined environments. An onboard camera is mounted on the robot to capture real-time video and images, which are transmitted wirelessly to the operator for monitoring and analysis.

The Arduino-based control system coordinates locomotion and camera operation, ensuring precise movement and data acquisition. The robot can be remotely operated, allowing users to inspect pipelines for cracks, corrosion, blockages, and structural defects without direct human intervention. This reduces risk, improves efficiency, and lowers maintenance costs.
